With England taking on Germany in an international friendly on Wednesday evening at Signal Iduna Park, the Gunners sent Alex Oxlade-Chamberlaine a message on Twitter to wish him good luck as training photos were released.
However, the way it was worded seemed to get fans into a bit of a state, as they actually believed that the club were saying goodbye to the midfielder instead.
The tweet read: “Best of luck in Dortmund!” next to a picture of the 23-year-old.
The following reaction was actually rather funny, with several users responding to the tweet with confusion and slight outrage at the possibility of letting him go.
Some fans were even prepared to unfollow the club account for apparently letting him go out of the blue.
Luckily, though, when the penny finally dropped there were red faces all round as they realised that they were in fact just wishing him good luck.
